I'm talking about the decades of mismanagement prior to now, specifically the policy of full suppression. Which was a policy for grasslands, chapparal, oak, mixed conifer, and every other vegetation type. Chaparral and brush are subject to land management practices, and do have specific sections in the California Forest Practice Rules regarding Fuel Hazard Reduction.
I'm from Ventura County and saw the Hill Fire firsthand, and was close to being evacuated because of it. I know what vegetation type that fire is burning in.
I was saying he was right, in that there has been mismanagement, but not by the state of California.

Technically speaking he wasn't wrong. Just graduated with a degree in Forestry from a California school. The fire problem is due to forest mismanagement, but not really in recent years. The US had a 70ish year long policy of complete fire suppression, and that allowed fuels to build up over time in areas that evolved to burn periodically in shorter intervals. This is one of the causes of the massive wildfires that we see today. That, combined with the fact that humans love to live in the wildland-urban interface, causes a lot of problems.
So technically he wasn't wrong, but he's also an idiot for thinking cutting funding is going to do anything but make matters worse.

I don't think he swept the leg. That looked to me like the guy on bottom was rolling, either to get away or for a knee bar or something. The guy who put the leg in was just following him during the roll. Probably wouldn't be a good takedown to try.

As /u/BgDog18 said, set ups are key. My go to set up in high school was the club-dig to high crotch, then switch to a double.

Basically you reach out (with your non-lead hand) and post it on their shoulder so they can't just shoot in on you, then with your leading hand club their head (not too hard, but hard enough to pull their head down). That will open them up to get the underhook. Once you have the underhook, the club hand goes down for the high crotch, then the underhook hand gets the leg, and switch off to a double. Here's a video of me doing that set up in high school. It was a bad finish on the double, but hopefully that shows the set up well enough.

Also, with double legs, don't try and shoot through them. Once you get their legs, push off your outside leg at a 90 degree angle and take them to the side. A good drill for that is to take drop steps into a wall, and practice exploding off to the side once right before you get to the wall.
